After a busy day prepping and conducting a full lunch service, the Chefs must clean up and do it all over again for dinner. Never before have the Chefs taken on such a huge challenge, and the judges are looking at everything from concept and food, to service and consistency, so no one is safe in the most daunting Restaurant War to date.

A showdown includes woks when the chefs visit San Francisco's Chinatown. Later, they must create a fast-casual restaurant concept. Foodies Martin Yan and Adam Fleischman make appearances.
